Abstract
With the introduction of the Renewable Energy Target (RET) and carbon pricing scheme
there has been a large increase in the amount of renewable generation being
implemented in the National Electricity Market (NEM). Renewable generation has two
main advantages being zero fuel costs and zero emissions output. This paper
investigates the benefits, disadvantages and incentives for the introduction of
distributed and renewable generation in the NEM. In order to become a more viable
investment choice the current market framework needs to be modified to better include
distributed and renewable generation sources. By making it easier and clearer for
companies to setup new distributed and renewable generators it creates more of
incentive for the generating companies to reduce their use of traditional high emissions
power plants and invest in renewable zero emission generators.
In this study the effects of distributed and renewable generation are observed from an
electricity market perspective. The simulations compare how the Locational Marginal
Pricing (LMP) and spot price are effected under different penetration levels of
Distributed Generation (DG). This was studied through the use of the modelling software
Matlab using the Matpower toolbox and PLEXOS. These allowed for different
penetration levels of DG to be placed throughout the IEEE 14-Bus test system.
Two new test systems were then built and analysed. They included an Australian NEM
model using PLEXOS and Matlab. These test systems were used to study the effects that
DG could have in the prevention of interconnectors contingency situations, that being
the inability to serve the required load. The final model used was based upon the IEEE
118-Bus test system. It was chosen as it is representative of an electricity network of
similar size to either NSW or QLD. This model was used to verify the most beneficial
location as to where DG placement should occur. The final simulations consisted of
modelling DG up to 30% in the IEEE 118-Bus model using solar and wind renewable
generation.

1. Introduction
The NEM consists of an interconnected network between Queensland, New South
Wales, the Australian Capital Territory, Victoria, Tasmania and South Australia.
Traditionally power generation in the NEM has been vertically integrated and centrally
dispatched. However due to the broad distance the electricity network covers it brings
with it very high capital costs for transmission upgrades and investment in new lines [1].
With the cost of residential electricity having risen by 91 per cent over the past 5 years
consumers have started to use power in a conserving manner [2]. As a result the demand
for electricity in the NEM has slightly declined and stabilised. Thus causing the new
generation investment outlook model in [1] predicting the generation investment cost
to be $26 billion. This is significantly lower than the previous prediction of $65 billion in
the 2010 NTNDP report.
Over the past few years there has been an increase in distributed and renewable
penetration in the NEM. The main driving force behind the increase in renewable energy
generation has been due to the mandated RET of 45000 GWh/yr by 2020 and the
introduction of the Australian carbon pricing mechanism which commenced July 1st
2012 [3]. A side effect of the increase in distributed and renewable generation is that
there are high costs associated throughout the levels of generation, transmission and
distribution. These costs are mostly due to the electricity network needing to be
upgraded due to reliability, safety and security reasons. However due the RET and
carbon pricing mechanism it is becoming unviable to build new coal-steam generation
units. Thus making distributed and renewable generation more prominent power
sources in the NEM.
The Australian Electricity Market Operator (AEMO) operates the NEM of which they are
responsible for its reliability and security [4]. As set out in the Australian Electricity Rules
(AER) each generator participating in the NEM power pool requires a connection
agreement with AEMO. The connection agreements generally split generation units into
scheduled, semi scheduled and unscheduled categories depending on their production
capacity and availability. Scheduled and semi scheduled generation are controlled
2
through a spot price market controlled by AEMO. The spot markets design means that
it is ideally based on the traditional centrally dispatched electricity market framework.
Distributed and renewable generation are located throughout the different levels of
power transmission and distribution. In order for renewable generators to participate in
the spot pricing market directly, complex prediction algorithms are required so that they
can make their day ahead bid offers to AEMO. Distributed and renewable generation
can also be used to reduce the cost of the local spot price. This can be made possible by
the distributed generating unit being operated in an islanded mode in its local
distributed network.
If the correct framework is in place it can be made possible for AEMO to schedule
distributed generating units at times of high electricity spot prices. Thus reducing the
average maximum cost of electricity at particular nodes. Distributed and renewable
generation can also affect the spot prices of adjacent nodes through times of high power
export.
1.1 Thesis Objectives
This thesis will cover the following objectives to help determine the effects distributed
and renewable generation have from an electricity market operational cost perspective.

include distributed and renewable generation,
Test the effects DG has on the operational costs of a power system by performing
static OPF with Matpower and dynamic power flow with PLEXOS,
Create a function that allows static OPF in Matpower to be ran at 48 intervals to
simulate dynamic power flow over 24 hours,
Determine possible incentives that will help increase the level of renewable
generation penetration in the electricity market.

1.2 Thesis Organisation
This thesis consists of six chapters with chapters 1 and 5 being the introduction and
conclusion respectively. In chapter 2 an overview of the existing NEM framework is given
to better understand how distributed and renewable generation are currently taken into
consideration. This chapter also covers the advantages and disadvantages of introducing
distributed and renewable generation into the electricity market from a system
operator’s perspective. It then explores current modelling methods that have been used
to study the effects of distributed and renewable generation in power networks. It
covers the existing factors that are contributing to the push for renewable power
generation into the NEM. Finally it introduces a proposed method of DG placement that
Local Distribution Companies (LDC’s) could use to make DG more attractive to investors
by offering benefits to both the LDC and investors.
Chapter 3 outlines the results of testing performed in the first half of the sessions. It
shows the effects of introducing DG at a single bus then moves on to model DG at
multiple busses. This analysis was used to study the advantages of DG in a power system
in regards to the spot price.
Chapter 4 then moves on to the most recent methodology and results obtained in the
final session of the thesis subject. This is split into two distinct sections with the first
being an overall NEM model and the second being a regional model using the IEEE 118-
Bus test system. The first section being the NEM model uses the two programs Plexos
and Matlab (matpower toolbox) to study the possible advantages of DG can play in
interconnector contingency situation (reduced line flow capacity). The second section
first reconfirms the placement strategy of DG then moves on to modelling the effects of
solar and wind generation could have at levels of 10, 20 and 30 per cent penetration
into a region the size roughly equal to that of NSW or QLD.
Finally in chapter 6 an outline of future work to be performed is given. This chapter will
provide an overview of how the current research can be furthered in order to include
the cost of operating renewable DG in a power system. Also it will touch on expanding
the model to include a wider selection of data and run over a longer time period.

2 Literature Review
2.1 Australian National Electricity Market
The electricity network on the east coast of Australia was traditionally a vertically
integrated system of state government owned and operated assets. In 1998 the NEM
began operation of the longest interconnected power system in the world [5]. The
introduction of the NEM has allowed for privately owned generation and transmission
assets to operate on the east coast of Australia. The electricity market is operated by
the AEMO [4]. A wholesale spot market is used by AEMO to operate the power pool
through which generator and retailers trade electricity. It is the responsibility for the
National Electricity Rules (NER) governing the NEM to be reviewed, amended and
expanded by the Australian Energy Market Commission (AEMC) [4]. It is the AER
responsibility to enforce the NER.
The growth in energy consumption has gradually declined over the past five decades
leaving Australia as the 18th largest energy consumer in the world [5]. With an abundant
supply of natural resources Australia’s generation mix consists of approximately 90%
non-renewables and 10% renewables [3]. Non-renewable power sources are mostly
coal, oil and gas. The renewable generation mix over the past decade has change
significantly. In [3] it can be seen that the hydro component of installed capacity of
renewable energy has decreased by 30% due to a significant increase in wind and solar
installation.
2.2 Wholesale Electricity Market
The traditional electricity market framework by which AEMO operates is based upon a
spot market through which electricity is bought and sold through a power pool [4].
AEMO follows the process of first determining the required demand level and gathers
generation offer prices. Once AEMO has determined the load it then schedules and
dispatches the generator using the generator offers by placing them in a bid stack [4].
They then calculate the spot price by measuring electricity use and generator usage. The
6
final step in the process is for AEMO to settle the market financially by paying each of
the generators for the electricity they have produced.
It is common though for most renewable and distributed generation units to not
participate directly in the spot market. This can be either due to their low power output
or intermittent power output which is reflected in their connection agreement [4].
However all power generation either large or small can have an effect on local and/or
neighbouring power requirements thus affecting the spot price. It could be in AEMO’s
interest to modify the electricity framework in such a way that they have control over
all distributed and renewable generation.
2.3 Hourly Spot Price
In [6] the hourly spot price, ρk(t), for the kth customer at hour t is defined as (1).
𝜌𝑘(𝑡) = 𝛾𝐹(𝑡) + 𝛾𝑀(𝑡) + 𝛾𝑄𝑆(𝑡) + 𝛾𝑅(𝑡) + 𝜂𝐿,𝑘(𝑡) + 𝜂𝑄𝑆,𝑘(𝑡) + 𝜂𝑅,𝑘(𝑡) (1)
𝛾𝐹(𝑡): 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛 𝑀𝑎𝑟𝑔𝑖𝑛𝑎𝑙 𝐹𝑢𝑒𝑙
𝛾𝑀(𝑡): 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛 𝑀𝑎𝑟𝑔𝑖𝑛𝑎𝑙 𝑀𝑎𝑖𝑛𝑡𝑒𝑛𝑎𝑛𝑐𝑒
𝛾𝑄𝑆(𝑡): 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛 𝑄𝑢𝑎𝑙𝑖𝑡𝑦 𝑜𝑓 𝑆𝑢𝑝𝑝𝑙𝑦
𝛾𝑅(𝑡): 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛 𝑅𝑒𝑣𝑒𝑛𝑢𝑒 𝑅𝑒𝑐𝑜𝑛𝑐𝑖𝑙𝑖𝑎𝑡𝑖𝑜𝑛
𝜂𝐿,𝑘(𝑡): 𝑁𝑒𝑡𝑤𝑜𝑟𝑘 𝑀𝑎𝑟𝑔𝑖𝑛𝑎𝑙 𝐿𝑜𝑠𝑠𝑒𝑠
𝜂𝑄𝑆,𝑘(𝑡): 𝑁𝑒𝑡𝑤𝑜𝑟𝑘 𝑄𝑢𝑎𝑙𝑖𝑡𝑦 𝑜𝑓 𝑆𝑢𝑝𝑝𝑙𝑦
𝜂𝑅,𝑘(𝑡): 𝑁𝑒𝑡𝑤𝑜𝑟𝑘 𝑅𝑒𝑣𝑒𝑛𝑢𝑒 𝑅𝑒𝑐𝑜𝑛𝑐𝑖𝑙𝑖𝑎𝑡𝑖𝑜𝑛
It is possible for this equations components to then be split into three main sub
equations representing System Lambda (2), Marginal Value of Generation (3) and
Marginal Value of Network Operation (4) [6].
𝜆(𝑡) = 𝛾𝐹(𝑡) + 𝛾𝑀(𝑡) [𝑆𝑦𝑠𝑡𝑒𝑚 𝐿𝑎𝑚𝑏𝑑𝑎] (2)
𝛾(𝑡) = 𝜆(𝑡) + 𝛾𝑄𝑆(𝑡) [𝑀𝑎𝑟𝑔𝑖𝑛𝑎𝑙 𝑉𝑎𝑙𝑢𝑒 𝑜𝑓 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛] (3)
7
𝜂𝑘(𝑡) = 𝜂𝐿,𝑘(𝑡) + 𝜂𝑄𝑆,𝑘(𝑡) [𝑀𝑎𝑟𝑔𝑖𝑛𝑎𝑙 𝑉𝑎𝑙𝑢𝑒 𝑜𝑓 𝑁𝑒𝑡𝑤𝑜𝑟𝑘 𝑂𝑝𝑒𝑟𝑎𝑡𝑖𝑜𝑛] (4)
System lambda consists of the “marginal fuel cost” and “marginal maintenance cost” [6].
This is the main component that is used when modelling generation since it takes into
account the cost of producing the required power output in units of $/MWh. When an
Optimal Power Flow (OPF) script is run in Matlab on a power test system it returns a
value of system lambda for each bus. It is this price that is used as the spot price for
modelling purposes.
The marginal value of generation and marginal value of network operations are
relatively small while the power system is operating below capacity. However in times
of high demand when a power system is approaching capacity these values can
significantly dominate the hourly spot price [6]. Hence it is necessary not to neglect
these when performing system analysis.
2.4 Market Modelling and Generator Cost Functions
There are a number of different methods that can be used to model the various aspects
of pricing in relation to distributed and renewable generation in electricity networks.
These include the use of the OPF feature of the Matlab toolbox Matpower [7] and also
market simulation software such as PLEXOS [8]. As a general rule distributed and
renewable generation is normally modelled as a negative load for ease of simulation [7].
This is mainly due to the intermittent nature of renewable power sources.
With the increase in demand and implementation of renewable technologies such as
wind and solar, advanced prediction algorithms have been developed [9]. The exact
details of these algorithms are beyond the scope of this report. However the idea itself
is predominantly essential due to the assumption that these prediction algorithms can
be used to determine a renewable generators day-ahead and 5-minute power output
[10, 11]. This information can then be used by the market operator in the process of
dispatching generators since;
𝑃𝐷𝑒𝑚𝑎𝑛𝑑 − (𝑃𝑤𝑖𝑛𝑑 + 𝑃𝑠𝑜𝑙𝑎𝑟) = 𝑃𝑛𝑜𝑛−𝑖𝑛𝑡𝑒𝑟𝑚𝑖𝑡𝑡𝑒𝑛𝑡 (5)
8
In [6], two dispatch models are used to examine the differences between “wind power
as a constraint in dispatch” and “wind power as a strategic bidder”. The first scenario
models wind as a negative load. This corresponds to the current process of dispatching
wind power as all renewable generation must be bought first. The second scenario
models wind generation as strategic bidders, thus allowing them to become key players
in the power pool. By allowing renewable generators to operate as strategic bidders a
large incentive is introduced since there is a large increase in the profitability of the
renewable generator [6]. The results of [6] indicate a profitability for future renewable
generators however this is at the cost of the consumer. In conclusion to this it can be
seen that the electricity market framework should be modified to benefit both the
generator companies and also the consumers.
In order to model generation sources appropriate generator cost functions are required.
These cost functions are used to determine the costs of running the generators based
upon required power output with respect to fuel and maintenance costs. Hence the
generator cost functions return a value equivalent to system lambda, λ-$/MWh.
Conventional generation sources such as coal and gas are used as the main sources of
dispatchable generation. With black and brown coal used for base load power and gas
used for intermediate power generation. Equation (6) is a second order polynomial that
is used to represent the cost function of coal and gas power generation [10]. The costs
generated through equation (6) are used in the determination of the spot price.
𝐹𝑖(𝑃𝑖) = 𝛼𝑖 + 𝛽𝑖𝑃𝑖 + 𝛾𝑖𝑃𝑖2 (6)
𝛾, 𝛽 𝑎𝑛𝑑 𝛼: 𝑐𝑜𝑒𝑓𝑓𝑖𝑐𝑖𝑒𝑛𝑡𝑠 𝑖𝑛 $/ℎ𝑟
𝑃𝑖: 𝑃𝑜𝑤𝑒𝑟 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑒𝑑 𝑖𝑛 𝑀𝑊

In times of high power demand hydroelectric power generation is often used as a
peaking power source. The main reason behind this is that they have a very fast start up
response time. When producing power hydroelectric generation has no fuel costs.
However peaking plants with a pumping cycle are modelled with the fuel costs that are
required to pump the water back up into the reservoir at a time when the spot price is
lower [6].
In order to model wind as a negative load its power output must be predicted so that
the market operator can schedule the remaining power necessary to maintain network
balance [10]. Prediction of the day ahead wind power generation can be achieved by
using equation (7).
𝑃𝑔𝑒𝑛 =1
2 𝜌 𝐴 𝑢3 (7)
𝑃𝑔𝑒𝑛: 𝐸𝑙𝑒𝑐𝑡𝑟𝑖𝑐 𝑃𝑜𝑤𝑒𝑟 𝐺𝑒𝑛𝑒𝑟𝑎𝑡𝑒𝑑 𝑓𝑟𝑜𝑚 𝑤𝑖𝑛𝑑 𝑖𝑛 𝑀𝑊

𝐴: 𝑊𝑖𝑛𝑑 𝑆𝑤𝑒𝑝𝑡 𝐴𝑟𝑒𝑎 𝑖𝑛 𝑚2
𝑢: 𝑣𝑒𝑙𝑜𝑐𝑖𝑡𝑦 𝑜𝑓 𝑤𝑖𝑛𝑑 𝑠𝑝𝑒𝑒𝑑 𝑖𝑛 𝑚𝑠−1
As wind power is one of the most mature forms of renewable energy generation
technologies its future reduction in cost is predicted to not be as significant as other
technologies [24]. This in turn allows for future implementation costs to be calculated
relatively simply.
10
As solar is also modelled as negative load it is necessary to calculate its day ahead power
generation using equation (9) as found in [10].

2.5 Introduction of Renewable and Distributed Generation in the NEM
DG may consist of a variety of generation types including renewables and non-
renewables. In the Australian NEM context power generation of less than 30MW is often
considered to be DG [12]. Sections 2.2.3 and 2.2.5 of the NER define the two main
categories of existing DG being Non-Scheduled and Non-Market generators respectively
[13]. However with the increasing rate of large scale renewable penetration into the
NEM it is becoming harder to define DG as the different generators can fall under the
majority of generator categories. The main factors that are effecting it include the
distributed power output, the availability of supply, infrastructure costs and also
connection fees as discussed in [12].
2.6 Renewable Energy Target and Emissions Trading Scheme
With the RET set at 45,000 GWh/yr for the year 2020 and the introduction of the
Australian carbon pricing mechanism [3] there has been a major increase in the
commissioning of renewable power generating units in the NEM. Since the NEM is
traditionally a vertically integrated centrally dispatched system it presents a set of
challenges that have to be overcome in order to integrate distributed and renewable
generation into the electricity network. This can be achieved by modifying the existing
market framework by which AEMO operates. In [24], it is predicted that once the carbon
price becomes greater than $50 per tonne the lower cost option of rebuilding the NEM
11
will be with renewable energy. Since NEM coal and gas generators would be
“considerably more” expensive, if faced with international prices [24], it is highly likely
that these cheaper conventional forms of generation will become significantly more
expensive if the resources could be easily sold on the international market. With the
introduction of liquefied natural gas terminals on the east coast of Australia this has a
high probability of occurring. Thus in turn will act as an incentive for electricity
generation companies to invest their money elsewhere in other technologies such as
renewable generators.
2.7 Effects of Renewable and Distributed Generation on Electricity
Market
Renewable and distributed generation can have many effects on the electricity network
of which must be taken into consideration into the electricity market framework.
Market regulations and framework play a significant role in the process of
commissioning new generators. One current deterrent in the NEM is the fact that all
generators no matter their size have to pay the same connection fee if they intend to
participate in the power pool [14]. There is also a great deal of manual processing of
each application due to AEMO not having a standardised approach to small generator
registration [14]. If the correct framework were to be put in place then small generators
could operate more freely in the power pool.
Although a framework that were to include small distributed and renewable generation
would increase the costs due to the complexity of monitoring and running the network.
It would however provide a much more efficient and secure electricity network. The use
of DG and renewable generation as the ability to reduce the future cost of localised
electricity as the technology further develops and becomes cheaper to install and
operate. As the level of renewable generation penetration increases throughout the
network, the required level of conventional generation will be offset. This will not only
extended the lifespan of the finite fuel source, but also significantly reduce the amount
12
of emissions produced by the electricity network. Finally by introducing a set of market
regulations that allows distributed and renewable generation to be introduced and
operated in the electricity network it will open many new doors for different jobs.
Electricity market frameworks vary between the different power systems throughout
the world with the main difference being how the power pool operates. The Nord pool
in Scandinavia is optional as opposed to mandatory in Australia, England and Wales [12].
However in California it is only mandatory for the three main private utilities, ensuring
no one utility can achieve full market power. An advantage of the Californian market
framework are the incentives present in the fee structure. Unlike the Nord Pool,
Austraian NEM and the England and Wales annual fixed fees, there is only a one time
application fee in California [12].
The introduction of a new law in California will require utilities to get 33 per cent of their
electricity from renewable sources. The proposed decision [26] will require up installed
energy storage to reach 1.3 GW by the year 2020. This will be spread throughout the
three main utility companies; Southern California Edison (580 MW), Pacific Gas and
Electric (580 MW), and San Diego Gas and Electric (165 MW). As a result of this it is very
likely that energy storage technology will become significantly more affordable during
this time.
Germany is another country that is leading the way in terms of renewable and
distributed energy penetration. The German government has revised aconcept of 50 per
cent renewable in the gross electricity consumption until 2030 as well as well as a
complete renunciation of nuclear power until 2022 [27]. By the end of 2011 the
renewable energy generation in Germany had already exceeded 20% gross electricity
generation [27]. The grid-regulating Federal Network Agency has stated that energy
storage in the possession of grid operators is not allowed to operate in the markets while
not being used for grid support. Another future framework proposal is that a storage
13
operator could be introduced into the market which will work in conjunction with the
market operator.
The implementation of distributed and renewable generation has the ability to reduce
the LMP [15]. As the LMP is the price to provide the required energy for each bus for the
next unit of demand it directly effects the overall spot price. Thus by distributed and
renewable generation being present throughout the network it has the ability to
maintain an overall lower spot price. It is capable of achieving this by having busses use
the cheaper locally generated electricity first before they import from centrally
dispatched generation.
In [15], a 5-bus test system was designed and implemented in Matlab. This model
consisted of three centrally dispatched generators and one large wind generator
representing a 14.6% renewable penetration level. The results of this paper indicate that
a large amount of money is able to be saved as the wind generator is capable of
supplying a large portion of load previously supplied by an expensive centrally
dispatched generator.
Distributed and renewable generation are already affecting transmission investment
requirements. Schemes such as RET and government incentives have significantly
increased rooftop solar generation and hot water throughout the NEM. It is believed
that the recent solar increase has accounted for 53 per cent of the reduction in energy
demand since 2008 [2].
The NEM has interconnector transmission links which allow the trade of electricity
between its 5 regions [2]. This allows each region to draw electricity from neighbouring
regions during times of high electricity demand [2]. As the introduction of DG increases
the amount of power generation capacity will increase throughout each region thus
minimising the need for the capacity of interconnectors to be increased. In [1] it is
estimated that the new investment in transmission is $4 billion over twenty years which
14
is considerably lower than the previous estimate of $7 billion over twenty years.
However there will still need to be transmission investment to cover the costs of
upgrading aging assets, addressing local transmission issues due to new generation and
addressing medium and low voltage transmission and distribution needs [1].
A study in [25] suggests that the most beneficial option for future interconnector
investment is a northern ac option that joins Wilmington in SA to Mount Piper in NSW.
This interconnector option however would run through Broken hill, thus enabling large
amounts of wind generation to be connected at both SA and NSW and fed throughout
the system.
Microgrids are low or medium voltage distribution networks consisting of distributed
and renewable generation, possible storage devices and controllable loads with the
ability to be operated in grid-connected or islanded mode [16]. Microgrids have the
ability to improve the reliability and security of the electrical network if included in an
economic dispatch system due to the large diversity of generators [10]. Currently there
is much research underway to determine the most cost effective ways to operate
microgrids. The economic dispatch in each microgrid can vary significantly depending on
the generator types and load profiles.
In order the operate a microgrid efficiently a balance between local generation costs,
energy purchased from the main grid and energy sold back to the main grid needs to be
established [16]. It is suggested in [16] that the hierarchical control architecture be split
into three categories; Distribution Management System (DMS), Microgrid Central
Controller (MGCC), and Micro Source Controller and Load Controller (MC and LC).
Integration into to the NEM would require the central controller AEMO to have control
over the DMS while having the MGCC operate the microgrid locally. Local control over
the microgrid enables a high degree of local optimisation [16], and also reduces the need
for AEMO to perform a large amount of complex optimisation calculations.
15
In [10] an economic dispatch model was implemented to study the effects of wind and
solar implementation in an islanded microgrid with conventional and combined heat
cycle generation. The results of the simulation indicate that by including renewable
energy credits and wind energy into the microgrid the total cost of generation can be
reduced.
In [20] a model is used which optimises the Local Distribution Company’s (LDC) choice
of DG placement and development approval based upon submissions from Small Power
Producers (SPP). As each LDC has the most accurate knowledge of the requirements of
their local distribution network they can easily assess the benefits and disadvantages of
DG connection points. To help benefit each of the LDC’s and SPP’s each LDC could create
a DG priority connection list which they share with SPP’s. The process could be based
upon the following procedure;
1. Each LDC creates a DG priority connection list based upon their individual
network requirements.
2. Individual SPP’s submit their own design proposals based upon the requirements
set out in the LDC connection requirements.
3. The LDC chooses the proposal (if any) which best suits their requirements.
4. AEMO assess and process the application ensuring that it meets their standards.
5. Once approved the SPP builds/commissions/operates the new DG in the
distribution network.
16
2.8 Simulation Software Packages
There have been many market modelling simulations run on MATPOWER to study the
effects of distributed and renewable generation in electricity networks. In [15] a wind
farm is implemented between a generation and load bus. The system was designed to
reduce the need to schedule the second conventional generator with a much higher
operational cost. The results of the simulation show that as the generation from the
wind farm increases, the generation needed from the secondary conventional generator
decreases. Thus resulting in a decrease in the cost to serve the load. In [17] it is also
shown that the gain that wind farms can make while operating as strategic bidders
outweighs the cost of not being able to produce power in times of low wind.
Another report includes [28] which presented a methodical approaching into how
conventional DG could be placed into a power system by using the IEEE 118-Bus test
system. The results of this report indicated that it was possible to reduce the LMP in a
Standard Market Design (SMD) with the introduction of DG. This also led to larger more
expensive conventional generators to become redundant.
Unlike in the Matpower OPF test systems it has not been found in PLEXOS as to how
reactive power can be modelled. This bought with it the challenge of building the 14-
Bus test system in PLEXOS and getting reliable results. The generation coefficients had
to me modified in PLEXOS in order to achieve a cost-to-load price that corresponded to
that observed in Matpower. However as reactive power is not traded through the spot
market it was not taken to be a significant concern.
As Matpower performs the OPF simulations it can be used to model the stability of the
system at different loads and generation at set values. Since PLEXOS operates as a
dynamic market model it has the ability to perform economic dispatch on a varying load
profile. By using these two programs in conjunction with each other it is possible to
determine the stable load levels and LMP using Matpower, then perform economic
17
dispatch to determine the generation costs and cost-to-load using PLEXOS. The use of
the economic dispatch in PLEXOS can also be used to determine the amount of DG
required in a system to avoid the scheduling of the highly priced generator.
PLEXOS is used throughout multiple countries for the use of power market modelling
[8]. It has the ability to include or exclude a significant number of different variables that
are not easily modelled in other software packages. Companies such as AEMO use the
software to simulate the current power market but also future development plans.
Using the knowledge learnt of matlab and Plexos over the duration of the thesis a NEM
model was created in each program. This model was used to study the effects that
interconnector ratings could have one the NEM.
18
3 Previous Outcomes
The expectation of the preliminary thesis in respect to testing and modelling was to
reduce the average and peak LMP’s which would lead to a reduction in the spot price.
As DG was implemented it was found that the LMP would reduce at the point of
connection and neighbouring busses. The introduction of DG across multiple busses
resulted in a more significant reduction in the spot price as compared to implementing
DG on a single bus.
3.1 Implementation of DG at Different Busses
A systematic approach was taken throughout the testing and simulation process. Initially
the 14-Bus test system was studied in order to develop an in depth understanding of its
design and components. Once the base results had produced incremental sizes of DG
were then implemented. This was done so as suggested in [7] and modelled as a
negative load. This then led to the design, testing and analysis of a 10-30% DG
penetration level placed at strategic bus locations.
Before any DG was implemented a reference line was graphed at the location of the
second highest LMP. This process was used to clearly visually indicate which bus had the
highest LMP. By modelling DG as a renewable source it could be modelled as a negative
load and had no generation costs associated with it.
At a level of 30% DG the LMP across the system became relatively equal for each of the
load busses. Figure.1 shows the comparison between the LMP of each bus at the
different levels of DG implementation.
19
Figure 1: DG Effect on Cost in 14-Bus System
In Figure.1 it can be seen that as the percentage of DG increases the average LMP is
reduced. Initially the introduction of DG has very little effect on the LMP however as it
approaches the RET of 20% renewable energy penetration it drops by almost $2 /MVA-
hr. As the penetration level increases further to 30% the LMP drops by approximately
$4.5 /MVA-hr.
20
4 Methodology and Results
4.1 NEM Model
The load data used for all simulations was obtained from AEMO for the period of January
1st 2009. This date was chosen as it was used in previous models in other studies, as well
as the necessary wind and solar data only being available for this date. The daily load
data can be seen below in Fig. 2 and also Appendix C.1.
Figure 2: 1st January 2009, NEM Load Data [18]
The generator data used in the creation of the NEM model was based upon the same
information used in [18] which was obtained from [19]. This generator data used for
each state can be seen in Appendix C.2.
The interconnector data however was obtained from [23] and is shown Fig. 3 and Fig. 4.
21
Using the original Generator and Interconnector data the following PLEXOS model was
created and its overall layout drawn in Microsoft Visio for easier interpretation as shown
below in Fig. 3;
Figure 3: PLEXOS NEM Model Layout
The above model was created in PXOS using all referenced in this section. This process
took a considerable amount of time as an understanding of the program had to be
developed. There were also a few issues when verifying it against some of the results
obtained in [18]. An exact replica could not be produced however it was very close. After
extensive testing and analysis it was believed that the differences were most likely due
to inconsistencies between the two data sources [18] and [19] as well as other variables
and constraints that may have also been implemented. Another difference was that the
model in [18] used different interconnector values. However testing confirmed that it
did not affect the system relative to the differences observed. Overall though the model
created produced results that were very similar to that in nature of real life NEM power
flow and appropriate pricing.
22
The NEM model created in Matlab was designed based upon the previously created
PLEXOS model. However due to the differences in the programs the two models could
not be created identically. To compensate for this the Matlab model was designed to be
as similar as possible to the PLEXOS model and converge with a cost-to-load value within
0.1% difference. As the Matpower OPF in Matlab is based upon static simulations only
the data for the first period of January 1st 2009 was used for this section. The reason for
using this one load data set alone was due to simplifying the model as well as
observations to be made not requiring changing load data.
The numerical values for the generator cost functions were taken from [18] and scaled
until the program converged within the set 0.1% tolerance. It was found that the scaling
factors for the generator polynomial coefficients were 0.1 and 1.265 respectively. These
can be seen under section “Generator Cost Data” in Appendix C.3.
Table 1: Cost-to-Load - Verification
MATLAB PLEXOS
Cost-to-Load ($/period) 208082.55 208341.37
As Matpower models the interconnectors differently to PLEXOS the interconnector
values were slightly different and can be seen in Fig. 4. The main difference being that
the rating of power flow was equal in both directions.
23
Figure 4: MATLAB NEM Model Layout
The NEM model created in matlab as shown in Appendix C.3 was designed to perform
just one OPF for the first period of load data for 1st January 2009 as it made it easier to
verify against the Plexos model. The other main reason for not designing this system to
operate for the 48 half hour periods of the day was due to it being designed to simulate
interconnector capacity restrictions. Thus the only variable that would be required to be
changed would be the interconnector’s ratings.
Another difference that was observed was that the LMP for each state was different.
However the final objective function value was very similar between the models. If the
model was required for other types of analysis it would be best to modify it so that it
was as similar to the Plexos model as possible.
24
One of the main causes of high electricity spot prices is the inability to serve the required
load. This can occur by a number of different ways, with the loss of an interconnector
being one of the most severe during times of peak load. In order to observe the effects
of this the PLEXOS and Matlab models created were modified to simulate a contingency
situation on the VIC-TAS (BASSLINK) interconnector.
The interconnector between TAS and VIC was set to 5% capacity (24MW). The MATLAB
and PLEXOS models were then re-run. It was expected that the price to serve the load
should have increased noticeably due to the inability to export cheaper power between
TAS and VIC. However the Matlab model failed to converged as the load at TAS was
unable to be served thus invalidating the OFV. In PLEXOS a valid result was produced as
the cost to serve the load increased to 3255430.08$/period and TAS was required to
dump load as a result of insufficient power supply.
Table 2: Cost-to-Load - BassLink @24MW
VIC->TAS = 5%(24MW) MATLAB PLEXOS
Cost-to-Load ($/period) N/A 3255430.08
Since the MATLAB function did not converge with an interconnector value of 24MW
between TAS and VIC, the value was set so that TAS would be required to operate its
generators at 100% and MATLAB should also achieve convergence. This value was found
to be 289MW (IC rating = T LOAD – T Gen) and was entered into PLEXOS in order to compare
the results. As the MATLAB model converged it was expected that there should not be
a significant price difference in the cost-to-load, however it should increase due to TAS
needing to operate at 100% generation. The following results in Table 3 were found;
25
Table 3: Cost-to-Load - BassLink @289MW
VIC->TAS = (289MW) MATLAB PLEXOS
Cost-to-Load ($/period) 208631.85 4591480.97
Initial analysis of this result leads the observer to believe that this result is incorrect.
However the huge difference in price is due to the differences in the two programs used
and also the models created for each as they are not identical. In the MATLAB model the
OFV remains low as the system is still able to support the TAS load (requirement of
convergence). On the other hand the PLEXOS program has the capability to dump load
when required. This is a result of generation not being able to meet the required load
with leads to the repercussion of reaching the ceiling price ($10000 as PLEXOS default).
Thus leading to the dramatic increase in the overall cost-to-load. Fig. 5 below represents
the financial consequence of generation not meeting demand:
Figure 5: Bass Link Contingency Situation 1
The implementation of DG has the ability to benefit this situation as the increase in local
distributed generation can result in the reduction in number of interconnector
26
contingency situations. Figure 6 is a representation of the effect 21MW of DG would
have for the situation shown in Fig. 5:
Figure 6: Bass Link Contingency Situation 2
For the first period alone the addition of 21 MW DG would create a saving of (4591480-
193757) 4397723 $/period. In reality the occurrence of reaching the ceiling price is
relatively uncommon and does not stay at a sustained value as shown above. The reason
for the model being set this way is to show two things; the financial penalty faced in
contingent situations, and the ability DG can have in reducing relatively volatile prices
during contingent situations.
These results indicate two main outcomes; the first being that MATPOWER is not
capable of providing valid results once it is unable to achieve convergence in its power
flow whereas PLEXOS has the ability to dump load, and the second being that DG has
the ability to minimise the occurrence of the ceiling price being met as it provides
additional generation to the system.
27
The PLEXOS NEM model was then modified to generate 24hr results for different
limitations on the Victoria to Tasmania, Bass Link connection. The 24hr total cost-to-load
for ratings of 100%, 98%, 96%, 94% and 50% (480, 470, 460, 450 and 240 MW
respectively) were implemented and are shown below in Fig. 7
Figure 7: NEM Contingency Analysis
The results above are not identical to that of which occur in reality due to Tasmania
having a significant amount of hydro generation which has not been modelled due to
time constraints. However the results are representative of the significant effect IC
contingency situations can have on a region if the region heavily reliant on the IC to
support their daily load. Once the rating of the Bass Link IC falls to a value that results in
the supplied electricity generation being less than the load, the volatility of the cost to
the system will be very similar to that shown in Fig. 7.

Below in Fig. 8 the periodical spot prices are shown for normal operating conditions for
conventional generation in the NEM for 1st January 2009 with the Bass Link IC operating
at 100% rated capacity (±480 MW).
Figure 8: Spot Price - Bass Link @480MW
The average spot price for Tasmania is significantly greater in Fig. 8 above as it is required
to import a large proportion of its generation requirements due to the total local
generation being relatively small in comparison to its load.
Figure 9: Spot Price - Bass Link @470MW
In Fig. 9 the reduction of the IC rating down to 470MW results in the spot price hitting
the models ceiling price of 10000 $/MWh between periods 41 and 42. This results in the

jump in the daily cost-to-load as seen in column 2 of Fig. 7 from $9606956.15 to
$20168080.75, a cost increase of 210%. Thus from these results DG should be
considered as a solution to reducing the regions dependency on the interconnector. DG
and renewables are not always favourable due to their large initial costs. However since
they have the ability to reduce the likelihood of IC contingency situations occurring the
implementation of DG is a benefit to the entire NEM as it help avoid these expensive
situations. As DG has the ability to reduce the transmission requirements it in turn
offsets the transmission investment costs required, while at the same time actively
supplying the region with electricity. This has the lead on effect of reducing the
requirements of conventional centrally dispatched generation. Thus reducing the
demand on fossil fuels such as coal and gas, resulting in an increased lifespan of these
resources.

4.2 MATLAB 118-BUS DG Modelling
The 118-Bus test system was chosen as it best represents that of a network of similar
size to the NSW and QLD regions. Thus allowing for an analysis on the effect that large
scale DG and renewable penetration could have at a regional level throughout a large
power system such as the NEM. The topographical layout of the 118-Bus model is shown
in Fig. 10. However due to the poor clarity further reference can be taken from the IEEE
118-Bus model freely available in the Matpower toolbox for Matlab.
Figure 10: 118-Bus Test System Topography
31
The 118-Bus model “case118.m” was ran using the matpower toolbox in Matlab. The
results were then used to plot the load and LMP of each bus as shown in Fig. 11.
Figure 11: Load and LMP of Each Bus in the 118-Bus Model
Before starting the renewable DG modelling a test was first performed to confirm that
it was more economically viable to implement DG on the most expensive LMP buses
rather than the most loaded busses. To achieve this 0-10MW of DG was modelled using
the negative load approach on first the most expensive LMP busses (41 and 44
respectively) and also the most loaded bus (59) in separate simulations. Using the LMP
out of each set of results an array was created and used to plot the effects the DG steps
had on each of the test cases. This was used for a visual comparison and can be seen in
Fig. 12 and Fig. 13.
32
Figure 12: DG Effect on LMP when Placed on Most Expensive Busses
Figure 13: DG Effect on LMP when Placed on Most Loaded Busses
From the results shown in Fig. 12 and Fig. 13 it can be seen that it is more effective to
implement DG on the more expensive LMP busses rather than the most loaded busses.
Thus concluding the assumption was correct due to Fig. 12 being showing the LMP being
more sensitive to change when DG placement is based upon existing LMP prices. In
conclusion to this finding all DG implemented in further simulations will be based upon
the LMP prices in descending order.
33
As stated in [15], most power systems will be able to reliably handle a penetration level
of up to 30 per cent renewable power generation without significant alterations thus a
value of 30 per cent was chosen. This value is greater than the 20 percent RET total
however it allows for some of the generation lost due to intermittent renewable supply.
Thus it means that there is a much greater chance that 20 per cent of generation will be
supplied by renewable generation more often.
In Excel the 118-Bus LMP data was sorted into descending order. Using the automatic
sum feature the number of busses required to produce 10, 20 and 30 per cent renewable
generation were found. This was achieved by selecting the busses in descending order
of LMP that gave a vale slightly higher than the generation requirements. Selection was
done in this manner to maintain a positive load on each bus at all times. The generation
targets and number of required busses are shown in Table 4. The generation data and
required scaling factors can be seen in Appendix D.1;

Initially 48 period solar irradiance data was obtained from [21] for 1st January 2009 at
Wagga Wagga, NSW, Australia. This data was required as it is representative of the ‘St’
variable in equation (9). The solar irradiance data can be seen in Appendix D.2. The
“case118” matpower script was modified into three new functions;
case118_CaseSolar_010, case118_CaseSolar_020 and case118_CaseSolar_030. Each
using the scaling factors calculated in AppendixD.1. The modified ‘mpc.bus’ section of
the matpower function for 30 per cent solar penetration levels can be seen in Appendix
D.3. The new solar case files created were modified to allow for the variable Et, total
solar generation, to be passed into them and used throughout as the variable Psolar.
This variable, Psolar, in conjunction with the scaling factors allowed for the solar
generation to be modelled as a negative load as shown in the extract of code in Fig. 14;
Figure 14: Solar Power Implementation in Matlab
Figure 15 is an extract of code used to compute the results for each of the 48 OPF
simulations ran;
Figure 15: Solar Penetration Data Loop
35
Figure 16: Average and Peak LMP 24hr Prices for 10% Solar Penetration
The results in Fig. 16 indicate that at a value of 10 per cent Solar penetration spread out
upon the first 15 of 180 most expensive busses the peak price is reduced to 40.53 $/hr
down from 41.25 $/hr, a saving of 72 c/h. This could be considered only a small saving,
however in the case of a conventional generator needing to switch off for maintenance
or in the event of a trip during the day it could be of great financial benefit. This is due
to the additional power supplied by the network via the solar PV generators. In order
for the solar to be of a greater financial benefit a more expensive conventional generator
of the same output capacity could be decommissioned or re-categorised to operate as
a peaking plant if required. As the nature of the curve in Fig. 16 is relatively flat
throughout the majority of the day it indicates that the price will remain relatively stable
and predictable at a 10 per cent penetration level. Thereby reducing the complexity
required for the market operator when estimating the spot price.

Figure 17: Average and Peak LMP 24hr Prices for 20% Solar Penetration
Upon implementation of 20 per cent solar penetration it was expected that the curve
would follow that of Fig. 16 with a reduced floor price and a sharper descent into the
generation and sharper ascent out of the generation time. Thus approaching a square
step function. However after simulation it was found that for 20 per cent penetration as
shown in Fig. 17, the floor price decreased but dipped down to a central point when
solar penetration was at its maximum.
The original prediction for the final simulation of 30 per cent solar was similar to that
predicted for 20 per cent with the peak price representing a unit step function. However
from the previous results found for a 20 per cent penetration level it was predicted that
the curve would either flatten out again as in Fig. 16 or the peak in the minimum floor
price would reduce.

Figure 18: Average and Peak LMP 24hr Prices for 30% Solar Penetration
After performing the final simulation for a penetration level of 30 per cent solar
generation it was found that the shape of the curve for the maximum LMP price started
to resemble that of the average LMP price for the day as shown in Fig. 18. A comparison
of the average spot price for each of the penetration levels as shown in Fig. 16, 17 and
18 shows that they all follow a similar curve shape. However at a 10 percent penetration
level solar only offers a slight benefit and may not be financially viable. Whereas at a
penetration level of 20 per cent and greater the renewable generators start to create
significant reductions in the LMP.

The wind penetration models were created in the same manner as the solar models. The
difference being that they simply used a different power generation equation and wind
data was used in this section instead of solar data. To calculate the wind power
generated equation (7) was used. The wind data was obtained from [22] and can be seen
in Appendix D.4. Figure 19 is an extract of code used in the simulation to generate the
wind penetration results for the same 24 hour period;
Figure 19: Wind Penetration Data Loop
As the electrical power produced by wind turbines is proportional to the wind speed
cubed its power output curve is random in nature. Unlike solar with which it is known
what time the sun rises and falls while being predominantly affected by shading, wind
speed is complex to predict. Even once wind speed and the power in the wind is
predicted it is still very volatile in nature with its intermittency. Thus leading to the
importance of turbine location to ensure the power supply is as constant as possible.
Initially all three penetration levels were performed using the wind data from one
location. This in reality is not ideal as it is not practical to implement these sizes of wind
generators all in one location. Due to the significant changes in power output this
scenario would be dangerous to the electricity network for reliability reasons. However
for the first section of this test it is justified as it allows a quick analysis of the overall
benefits and disadvantages that wind turbines can have.

Figure 20: Average and Peak LMP 24hr Prices for 30% Wind Penetration
Figure 20 indicates that wind turbine generation can offer significant cost reduction
advantages as seen by the LMP reaching a minimum of $37.50 in the last period of
simulation. However due to the turbines intermittent behaviour in output power as
shown in Fig. 21 the wind turbines should be spread out over a vast area.
Figure 21: Wind Power Generated for 30% Wind Penetration
The results obtained above are not an accurate representation of the overall benefit
wind generation offers as all generation has been calculated from a single set of wind
speed data (Broken Hill Airport). In order to observe the benefit of this type of DG wind
speed was initially taken from 3 different locations (Broken Hill Airport, Rundle Island
and Learmonth Airport). The Wind speed data can be seen in Fig. 22 as well as the
average;

Figure 22: Wind Speed and Peak LMP using 3 Separate Regions
From the results in Fig. 22 it can be seen that by distributing the wind penetration over
multiple locations the overall spot price is only slightly reduced, minimum LMP of
$40.18. This is predominantly due to peak generation being constrained to have full
rated wind speed at every turbine site simultaneously. A suggestion to this would be to
design the system based upon an overall average wind speed value rather than a peak
value of low probability which will cause an increase in the capacity factor. The above
model relies upon each region supporting 1/3 of the required renewable wind
generation. This however is significantly affected by the constant low wind speed Ut_3
(Learmonth Airport). Thus the simulations indicates that it would not be wise
implementing wind turbines in areas of low wind speed.
The data for Ut_3 was then removed to confirm whether it would in fact be financially
beneficial to remove the low wind speed data. The results in Fig. 23 confirm that it is
slightly more beneficial to implement wind penetration with the reduced number of
regions which have a higher average wind speed. This is shown by the LMP reaching a
minimum value of $39.30. The small change in LMP for the 3 wind speed model as
opposed to the 2 wind speed model was predominantly due to the heavy weighting on
each of the generators (1/3 each). The wind turbine generators in the 2 wind speed
model have an even greater weighting however due to their higher average wind speed
they have the ability to produce a significantly greater amount of power.

Figure 23 illustrates that the average wind speed and peak LMP are still fairly volatile
throughout the 24 hour period modelled. In order to try and overcome this volatile
nature a model closer to real life scenarios was created. This model consisted of nine
separate wind speed data sets which can be seen in Fig. 24 and Appendix D.4.

the wind data. This is due to the system taking the average of the wind speed from the
nine different regions. As a result of the power generation now being less erratic the
peak LMP throughout the 24 hour period also smooths out. Thus indicating that a wide
spread of wind data on average will have less side effects in the overall electricity
network as the varying power supply is spread throughout the network. This makes it a
lot more viable at the large scale generation level as the complexity is reduced for the
market operator, therefore reducing their operational costs.
Figure 24 also illustrates that wind power generation is very attractive to investors since
it has the ability to generate significant amounts of power once the wind speed becomes
greater than half the turbines rated speed. As the wind turbine generation is further
increased its capacity factor should also further increase. This will in turn represent the
minimum amount of wind generation constantly being supplied to the power system.
43
Both wind and solar generation can be beneficial to the electricity network as they have
the ability to provide clean energy with zero fuel costs. However they are limited in
usability due to the intermittent nature of their natural fuel sources. They also suffer
from their large start-up costs that investors are required to put forward. Despite this
these costs will significantly reduce over time as the renewable generation technology
improves.
Solar generation is relatively simple to predict as it mainly depends upon solar
irradiance, temperature and shading. Whereas wind generation is more complex as it
depends upon the forever changing wind speed which affects the power output
exponentially. Thus leading to the trade-off between predictability and generation
capability. Solar is more predictable but is less efficient opposed to wind generation
being harder to predict but offers a much higher generation efficiency. The higher
efficiency of wind turbines and there significantly cheaper production costs has made
them very attractive to investors seeking to invest in renewable generation technology.
The added complexity of predicting wind power generation has in the past been a huge
hurdle for both investors and energy market operators. However over the last decade
prediction methods and accuracy have significantly increased. Thus resulting in the
capability of wind generators to be classed as semi-scheduled or even scheduled
generators. With the penetration level of renewable generation ever increasing it is
becoming more and more important for the market framework around distributed and
renewable generation to be clearly set out.
As wind farms are built throughout eh electricity network they will naturally become
fundamental generators constantly supporting a portion of the networks generation
requirements. They will also have the capability to support a larger portion of the
generation requirements but will require support generation from quick response
generators such as CCGT and hydro electric generators. Solar generation has the ability
to serve a large portion of load throughout the day. However it also requires support
from wind, CCGT and Hydro throughout the night time period. Thus is will be
44
fundamental to keep large conventional generators until large scale energy storage
solutions can be economically implemented.
Large scale energy storage would allow for the power system to comprise mostly of
intermittent renewable generators as excess power generated could be stored for times
of low generation. Renewable generation will hereby significantly reduce the emissions
produced by the power industry overall while also extending the lifespan of our natural
resources such as coal and gas.

5 Conclusion
In conclusion to this thesis it can be seen that the introduction of distributed and
renewable power generation can have significant benefits in electricity networks for
both market operators, generators and consumers. With the correct framework in place
the market operator will benefit as they will have a broader source of generation to
choose from. This will result in more complex operations needing to be performed by
the market operator, however it will increase the security of the electricity network
significantly. Also with the introduction of schemes such as RET and carbon pricing
placing mandatory renewable generation levels companies are starting to invest more
money into the construction of renewable generation sources. The main benefit for
consumers will be in the pricing of electricity. As more DG is placed throughout the
network the electricity price should reduce but also remain relatively stable due to the
large amount of generation.
The results of the simulations performed in conjunction with this thesis agree to that of
the results of other market simulations performed from an electricity market
perspective. The simulation results of this thesis show that it is beneficial to implement
DG and both large and small scale renewable generation into the electricity network. It
also shows that it is best to spread the implementation of DG in order to maximise its
effect on the electricity price.
The research performed for this thesis in conjunction with the results indicate that
allowing distributed and renewable generators to participate in the spot market creates
an incentive for large companies to invest in these technologies. With convention
generation having high emissions output and a finite fuel source it is in the best interest
of the NEM to become less dependent on these technologies and more dependent on
renewable and distributed generation.

6 Future Work
To further the research that has been under taken it is proposed that the simulations be
run on an existing network such as NSW or QLD. In order to implement distributed and
renewable generation optimisation algorithms will be used in order to maximise the
efficiency of the effect of DG. Once the ideal locations for DG have been identified
different types of DG will be implemented. This however will not be implemented as a
negative load as in these simulations. Instead the generator cost functions will be
implemented for the renewable sources. In order for the results to be liable existing
wind and solar predictions will be implemented as done so in this thesis. Since the
renewable generation cost functions rely on investment pay back cost, general figures
will be used as represented in other research.
The more advanced features of PLEXOS could be used to model the effects of distributed
generation on inter-regional trade of electricity as well as regional trade. To further the
PLEXOS model the state electricity networks of QLD, NSW, VIC, SA and TAS could be
designed and implemented into their regional nodes of the PLEXOS model. This however
would require all line, load and generator data for every state for it to be accurate. Most
of which is not freely available thus making it a very complex task to complete.
